Samsung LM561B LED package completes 6000 hours of LM-80 testing

Samsung Electronics has revealed that its LM561B, a high-efficacy mid-power LED package has completed LM-80 testing. LM-80 is a widely observed test for lumen maintenance developed and accredited by U.S. Department of Energy”s Energy Star program.

“Through the LM-80 standard testing, we have been able to affirm that our LM561B package is optimised for premium LED lighting applications that demand high efficacy and reliability,” said Bangwon Oh, senior vice president of LED Lighting Marketing, Samsung Electronics.

A positive LM80 test results should enable the LM561B product lineup to be widely accepted across a variety of LED applications.

The Samsung LM561B completed 6000 hours of LM-80 testing, and among the test results, TM-21 data demonstrated an L70 of 93,000 hours (Reported lifetime: 36,000 hours) under a 150mA driving current at an operating temperature of 85 degrees Celsius. This means that the LM561B will maintain at least 70 percent of the initial light output for a minimum of 93,000 hours, which will make the LED light more amenable to applications that require a high level of lumen maintenance.

The LM561B, which was introduced earlier this year, is designed for LED lighting applications such as LED tubes, LED ambient lighting, downlighting and retrofit lamps, and features 170lm/W light efficacy. The product line-up offers a wide range of colour temperatures and comes in three brightness levels, while providing quarter binning to better meet customer design needs.
